Be it known that I, JOHN P. TARNUTZER, ofthe cityand .county of Fond du Lac, and State of Wisconsin, have invented a. new and useful Improvement on Cultivators; and I do hereby declare that the following is :L

full clear and exact descri tion of the construction and o eration oi' the same reference beinv had to the annexed drawings, making a part of this specification, in which- Figure l is a horizontal or top vien'.

Figure 2 is a transverse section, showing frame E when raised.

A. is the main'izrame of the cultivator, upon which the wheels are. B lis a smaller frame resting upon the main frame. C is that portion of the smaller frame in shape of an are fastened upon the frame B, on the upper side of which are is placed a pinion rack, i'. D is a shaft, with pinion p on one end, which, working in the pinion rack, turns the smaller frame B, and having on the outer end a capstan-head, c, by which shaft D is 'turnedaround The shaft passes through the smaller frame at a point near the capstan-head. E is the frame of the cultivator, in which the cultivator teeth are fastened. This frame E is fastened into frame B by hinges, k h, said frame resting in front upon the are C, so that as the frame D is moved from right to left, and 'vice versa, the enltivator frame moves with it. F F are two rollers, hung to the front beam' of the main frame A by iron cyesand rods. The rods on each roller are fastened together by a chain, which passes over the sheave or roller s, and running vto upper part of frame E, where it is fastened. I) is' a. handle, by which frame E is raised. 'w 10 are Wings fastened to `frame E, to be raised at pleasure higher or lower to regulate quantity of dirt to be turned upon the plant.v t is a spring or arm for catching and holding up frame E when raised.

The following is a description of the operation of the machine: The driver with his foot can press upon the bars of the capstan-head c, and thus turning the shaft D the frame E is lifted laterally. Thisis done by the pinion turning in a pinion rack. In this way the cultivator may he guided to suit the position of the rows of corn or other plants. The rollers are for levelling the dirt and pressing down the weeds, so that the cultivator teeth may e'ectually cover them withdirt.

When passing over stumps, stones 82e., or taking the eultivator to and from the field, by lift-ing on the handle b the frame E is raised up, and turned up to the left far enough to be caught and held by the spring t, which is long enough to be within reach of the drivers hand. The raising` up of frame E also raises the rollers F F by means. of the chain passing over the sheaves.

I claim as my inventionf- The shaft D, with pinion p, and pinion rack 1, and eapstan-heafc, and movable frame B.

Also, the rollers F F and sheave s, upon which chain passes.

Also, the hinges L h, upon which the frame E is hung.

Also, the wings w w.

A lso, the movable frame B.
